Method and device for realizing flexible temperature takeoff function

The invention belongs to the field of thrust management, and relates to a flexible temperature takeoff function implementation method, which comprises the following steps of: calling data in an aircraft data storage module, and calculating a flexible temperature takeoff performance data table according to a flight plan of an aircraft; determining takeoff characteristic speed data according to the flexible temperature initial value information, and sending the takeoff characteristic speed data to a thrust limit checking module; then whether the selected flexible temperature meets thrust limitation and preset rules or not is checked, if yes, a flexible temperature instruction is generated and transmitted to the control instruction generation module, and the control instruction generation module generates an engine working state control instruction and a throttle lever position instruction according to the received flexible temperature instruction; the signals are respectively transmitted to an engine control sy
